A Glossary of Strange Car Noises

Have you been wondering, what on earth is that noise?! Below are what the most common strange car noises mean.

  • High-pitched sounds: If you hear this when you shut off your engine, it may be time to readjust or replace the belt, or check the radiator pressure cap. A whistling noise from under the hood may indicate vacuum leaks.
  • Ticking: If you hear regular ticking when your engine idles, turn the car off and allow it to cool down. Check the oil level or consider a valve adjustment if there is enough oil. A similar sound may be coming from your tires, which may point to tire wear and wheels being off balance.
  • Squealing: If there is squealing when you step on the brake, the brake pads may be worn and need replacing, which should be done rather quickly.
  • Whining/humming: When you’re going through curves and hear this sound, your wheel bearings may be worn.
  • Clunking: Clunking coming from under the vehicle may be a sign of issues with the shock absorbers and suspension system.

In the event the noise leads to a breakdown, you can also call Mercedes-Benz Roadside Assistance for help!
